Career

Adler appears in the Fox television series Glee as school bully Dave Karofsky. In the November 2010 episode Never Been Kissed, written to tackle the issue of LGBT youth bullying, Karofsky is revealed to be a closeted gay teenager. Adler had previously questioned his character's motivations, but was surprised by the scene in which Karofsky kisses the object of his bullying, openly gay student Kurt Hummel (Chris Colfer).

He received a positive response via the social networking websites Twitter and Facebook, and commented that he was "Glad to represent such a large group of people," expanding: "I've gotten so many messages from people all around the world these last couple of days thanking me because either they are Karofsky, they were Karofsky or they know a Karofsky."
